1D15.20 - High Road Low Road

Code Number:
Demo Title:
High Road Low Road
Path Lengths and Velocities
Area of Study:

The balls will start and end at the same height.  The route is different and hence the time that the ball takes will be different also.  Using the carbon paper will enable you to show that the balls have the same energy when they leave the track.
